Patent number: 8483687Abstract: An arrangement and method for radio network relocation of a mobile terminal (114) from a first base station controller (122) to a second base station controller (122?) by anchoring at least some SGSN functions with respect to the first base station controller; and relocating at least some RNC functions from the first base station controller to the second base station controller. RNC (124), SGSN (132) and GGSN (134) components may be integrated together, and the RNC (124) may be parented by an SGSN. Alternatively, RANAP SGSN functionality may be split between SGSN and RNC, RANAP and user plane signals may be relayed by the first base station controller to the second base station controller, and the first base station controller may act as an anchor.Type: GrantFiled: May 10, 2005Date of Patent: July 9, 2013Assignee: Nvidia CorporationInventors: Andrew Gordon Williams, Timothy J.

Patent number: 8428026Abstract: An apparatus and method for scheduling data transmissions in a wireless network is disclosed. A first value related to a buffer is transmitted to a user equipment (UE) by a network. The network also transmits an allocation message for an uplink transmission and receives data in response. The data is selected from the plurality of buffers of the UE in response to the transmitted first value and based on a second value.Type: GrantFiled: August 18, 2011Date of Patent: April 23, 2013Assignee: Intellectual Ventures Holding 81 LLCInventor: Timothy J.

Patent number: 8355350Abstract: Power control in a communication system (100) employing a Downlink Shared Control Channel (DSCH) and a Forward Access Control Channel (FACH) is described. The method includes, applying power control on the Downlink Shared Control Channel; deriving power control information from the power control on the Downlink Shared Control Channel; and applying to the Forward Access Control Channel the derived power control information from the power control on the Downlink Shared Control Channel in order to produce power control on the Forward Access Control Channel. The power control of the Forward Access Control Channel may be implemented by scheduling data in response to the derived power control information.Type: GrantFiled: December 15, 2004Date of Patent: January 15, 2013Assignee: Sony CorporationInventors: Peter Jonathon Legg, Timothy J.

Patent number: 8310993Abstract: A wireless network buffers and sends segments of transfer communication protocol (TCP) data to a user equipment (UE). The wireless network may count a number of the sent segments of the TCP data for allocation of uplink resources. The UE sends an uplink segment over the allocated uplink resources, which may include information indicating acknowledgment of receipt of the sent segments of TCP data.Type: GrantFiled: September 16, 2011Date of Patent: November 13, 2012Assignee: Intellectual Ventures Holding 81, LLCInventor: Timothy J.

Patent number: 8228864Abstract: A communication unit comprises a receiver for receiving a message sent on an allocation channel, packet identifying logic, capable of identifying a data type of the received message, operably coupled to buffer logic for buffering data packets to be sent to the second communication unit. In an active mode of operation, the receiver of the communication unit is capable of intermittently receiving the message sent on the allocation channel and transition to continuously receive the message sent on the allocation channel in response to either: the buffer logic identifying that data packets are to be transferred to the second communication unit; or the packet identifying logic receiving a communication resource allocation message and identifying resource allocation data therein.Type: GrantFiled: October 20, 2011Date of Patent: July 24, 2012Assignee: Sony CorporationInventor: Timothy J.

Publication number: 20120113911Abstract: An apparatus for use in allocating resource in a wireless communication system employing transfer communication protocol (TCP) based data transfer between a network and a wireless subscriber communication unit comprises a scheduler (428) located in the network, wherein the scheduler buffers a TCP data segment for downlink (DL) transmission. A transmitter is arranged to transmit the buffered TCP data segment to the UE; wherein the message indicates an allocation of DL resources plus sufficient uplink resources to transfer a stand-alone ACK data segment (530). In this manner, for example in large bulk data transfer cases, a reduced latency may be achieved that may lead to improved throughput, due to the fact that the overall throughput may be limited by the window size (i.e. number of unacknowledged segments) rather than the throughput possible across the air interface.Type: ApplicationFiled: September 16, 2011Publication date: May 10, 2012Applicant: WIRELESS TECHNOLOGIES SOLUTIONS LLCInventor: Timothy J.

Patent number: 8015313Abstract: A communication device is arranged to transmit data segments over an interface, wherein the communication device comprises transmission management logic. In response to receipt of a data segment for transmission over the interface, the transmission management logic is arranged to determine a sequence number of a data segment to be transmitted and compare the sequence number of the data segment to be transmitted with at least one pending sequence number of a previous data segment. Based on the comparison, the transmission management logic either discards the data segment to be transmitted if the sequence number of the data segment to be transmitted matches the at least one pending sequence number of the previous data segment; or adds the sequence number of the data segment to be transmitted to the at least one pending sequence number and transmits the data segment over the interface if the sequence number of the data segment to be transmitted does not match the at least one pending sequence number.Type: GrantFiled: March 4, 2008Date of Patent: September 6, 2011Assignee: Sony CorporationInventors: Timothy J.

Publication number: 20080080464Abstract: An improved acknowledgement (ACK) prioritization scheme is disclosed that provides ACKs with a lower block error rate (BLER) (as opposed to data) over an air interface, provides a separate radio bearer for ACKs, and successively increases the priority of ACKs for each retransmission required. A lower BLER target for ACKs may be achieved by an increase in transmit (Tx) power, additional coding for the radio bearer, or the use of diversity or hybrid automatic repeat request (ARQ) schemes. After packets are identified as either data or an ACK, they are sent to separate Tx buffers over separate radio bearers. Because the ACKs are transmitted over separate bearers and Tx buffers as compared to the data, ACKs are never queued behind the data, and are effectively prioritized as compared to the data. When retransmissions are required for an ACK packet, the scheduling prioritization is increased successively for each ACK retransmission required.Type: ApplicationFiled: October 2, 2006Publication date: April 3, 2008Inventor: Timothy J.
